In Germany December '7, 1934 1 Claim.

The device according to my invention is intended chiefly for use ingardening establishments, florists shops and by decorators for wavingand doubling over the edge of crepe paper employed, for instance, formaking decorative covers for flowerpots, bouquets, etc., and forcarrying out this work in a more uniform and rapid manner than ispossible by hand.

The feature of my invention resides in the provision of a funnel havinga spirally wound wall for bending the edge of the paper and introducingit between two rolls which are pressed together by a spring or weightand can be turned by a hand crank and which serve to wave and doubleover the paper while smoothing it.

One form of the device according to my invention is illustrated in theaccompanying drawing, in which Figure 1 is a front view of a piece ofcrepe paper having a waved and doubled over edge; Fig. 2 is a side viewthereof, partly in cross section on the line 2-2 of Fig. 1; Fig. 3 is afront view of the device, partly in section; and Fig. i is a side viewthereof looking towards the wide funnel opening, some parts in Figs. 3and 4 being partly shown by broken lines to show more clearly parts inthe rear.

Referring to the drawing, a board a, which may be clamped to a table, isprovided with a bracket b secured thereto by screws. This bracket has alarge bush 0 extending to one side (in Fig. 4 to the right-hand side)and a small bush d extending to the other side. In the bush 0 a shaft eis mounted, to one end of which a hand crank is secured, and the thickerportion of the shaft e located between the crank f and the bush 0 isfitted with a roll 9 having a groove at its circumference. In the bush(1 a stub shaft h is mounted, which is provided at one end with aneccentric 2'. The latter, by means of a ball bearing, carries a secondroll having a correspondingly rounded rim which engages the groove ofthe roll 9. To the other end of the stub shaft h a lever Z is securedwhich, owing to the action of a helical spring m engaging its free endand secure-d in a bore of the board a, presses the roll is against theroll 9 by means of the eccentric i. The board a. has further screwedthereto a slender 5 sheet metal funnel n, whose wall is spirally woundand whose axis is located at an acute angle to the common central planeof the roll 9' and the rim of the roll it and approximately at rightangles to the plane passing through the axes of both rolls, the narrowerend of the funnel n being positioned at a short distance from the pointof contact of both rolls.

The edge of the crepe paper to be doubled over is inserted in thedirection of the arrow l in Fig. 15 3 in the narrow gap 0 shown in Fig.4 between the adjacent portions of the outer winding of the wall of thefunnel n, pushed towards the point of contact of the rolls 9 and k andbent by the spiral Wall of the funnel n, as indicated at a: in Fig. 2.Simultaneously, the rolls are turned by the crank ,f in the direction ofthe arrows 2 and 3 in Fig. 3 and thus draw the edge of the paper whilesmoothing and waving it between them and doubling it over, as indicatedat y in Figs. 1 and 2, the paper with its waved and doubled over edgecoming out from between the rolls at 2, Fig. 3.

What I claim as my invention and desire to secure by Letters Patent is:

In a device for waving and doubling over the edge of crepe paper a pairof rolls, means for pressing together said rolls, means for turning thesame, and a funnel for bending the edge of the paper and for introducingit between said rolls, said funnel having a spirally wound wall andhaving its axis located at an acute angle to the common central plane ofsaid rolls and approximately at right angles to the plane passingthrough the axes of said rolls.
